Abstract: A sprinkler nozzle is configured for a sprinkler positioned at a distal end of a center pivot irrigation system. The sprinkler nozzle includes a connection part securable to the sprinkler, and a nozzle opening downstream of the connection part. A nozzle opening downstream of the connection part is part-toroidal shaped and partially blocked or skewed to control water flow to portions of the deflector plate according to a desired wetted area. The part-toroidal shape spans an arc less than 360 degrees. The nozzle enables a custom designed water application to complement the other sprinklers that are on the pivot and can be shaped to also apply water a distance beyond the end of the pivot pipe to match the application rate of the sprinklers along the pivot pipe.

Abstract: An automatic reversible arc assembly for a sprinkler includes a pair of primary stop members circumferentially spaced from each other by a first amount, and a pair of secondary stop members circumferentially spaced from each other by a second amount, different from the first amount. The primary stop members and the secondary stop members are coupled together and define a pivot assembly pivotable between a first position and a second position. A timer module cooperable with the pivot assembly is configured to hold the pivot assembly in the first position for a selectable period of time, after which the timer module enables the pivot assembly to pivot to the second position. The primary stop members are active in the first position, and the secondary stop members are active in the second position.

Abstract: A rigid mount orbitor sprinkler assembly incorporates a deflector plate configuration that is configured for both spinning/rotating motion as well as orbital or wobbling motion around the center of a spool assembly. The sprinkler incorporates structure to reduce drool that may fall in a concentrated area below the sprinkler and to prevent debris from sandy water or the like from accelerating sprinkler component wear. With reduced vibration, the assembly may be rigidly mounted on a center pivot or other supporting structure while achieving the advantages associated with wobbling and rotating sprinkler assemblies.

Abstract: A flow control device includes a housing with an inlet and an outlet and a flow conduit disposed in the housing. The inlet, the flow conduit, and the outlet define a flow passage. A valve seat is disposed in the housing downstream of the inlet, and a shuttle is movably disposed in the housing and displaceable between a closed position engaging the valve seat to close the flow passage and an open position spaced from the valve seat to open the flow passage. A sealed chamber is defined between the housing and the flow conduit. A port coupled with a source of pressurized fluid communicates with the sealed chamber, where the shuttle is displaceable between the closed position and the open position based on a pressure in the sealed chamber. The threshold water pressure for displacing the flow conduit may be adjustable by modifying the pressure in the sealed chamber.

Abstract: A weighted inverted sprinkler assembly adapted for use with a drop hose of an irrigation system is disclosed. The assembly comprises a coiled weight formed from a coiled wire, a sprinkler fluidly associated with the drop hose, and a coiled weight support structure. A pressure regulator may be provided in fluid associated with the irrigation drop hose and the sprinkler. The coiled weight has a shape that is selected for use with a particular sprinkler assembly. The shape may be an elongated shape for use with an elongated coiled weight support structure, a beehive shape for use with a pressure regulator having a collar to support the coiled weight, and a pear shape for use with a pressure regulator having a flared housing. The coiled weight is preferably formed from a single coiled wire although two or more weights may be used in combination in a given application.

Abstract: A gooseneck pipe includes a first pipe half having a first radiused centerline curve, and a second pipe half fixed to the first pipe half and having a second radiused centerline curve. The first and second pipe halves define a flow path. Cross-sectional diameters of the first and second pipe halves vary along the flow path. The varying diameters of the first and second pipe halves serve to mitigate pressure losses due in part to Dean vortices or secondary flow patterns in the flow path when a fluid is turned in the gooseneck pipe.
